New AI models now show incredible math skill, solving problems that had stumped mathematicians for years. But what about basic geometric abilities? In our new paper in PLOS Computational Biology, we investigate this in vision models: doi.org/10.1371/jour... 1/8

This paper shows kids count parts with known names less - eg, arms, wheels, wings, etc. Also they will count an object as “two” after seeing it cut before their eyes, and after just counting it as “one”. onlinelibrary.wiley.com/doi/full/10....

Without actually sending your scripts/data to other people, it can be hard to ensure others can easily use your materials. This looks like a great solution. Another cool feature is that users can also tweak scripts to see how conclusions can change when different parameters are used.

New w/ @drbarner.bsky.social in Cognitive Science! We explored how kids learn the “later-greater” principle — the idea that numbers that come later in a count are greater in magnitude. Turns out this simple property governing the count system doesn't come easy! dx.doi.org/10.1111/cogs... 1/6
